Accessing the Control Panel acting as a USB Mass Storage device

In this scenario, you are a local user who wishes to access the Control Panel through its USB interface. You are equipped with a PC.

1) Press the joystick to switch the Control Panel to USB device mode.

2) Connect the PC to the EVK1100 board USB plug.

Use the miniB-plug-to-STD-A-plug USB cable to connect the EVK1100 board and the PC. The LCD screen line 2 and 3 should change. Line 2 of the screen(the status line) should display a blinking USB icon meaning that a USB connection is up and running. Line 3 of the screen(the menu line) should display the information string "USB Mass Storage" meaning that the Control Panel is acting as a USB Mass Storage device.

3) Access the Control Panel Mass Storage memory.

There is no menu on the EVK1100 board in this mode. The Control Panel acts as a regular USB Mass Storage key in this mode. The PC sees the Control Panel as a removable disk: it has full access to the Control Panel file system.

4) What can be done in the USB Mass Storage device mode

5) Leaving the USB Mass Storage device mode

As you would for a regular USB key, it is best to:
  1. On the PC side: safely unplug the USB device through the Windows task stray,

  2. On the EVK1100 side, two possibilities:
    1. if the USB is used as the board's power supply: simply press the joystick to leave the USB device mode.
    2. else unplug the USB cable from the Control Panel's board.

Once the Control Panel has left the Mass Storage Device mode, the LCD screen should look like this (note that the USB icon disappeared from line 2 and that the message " Set as USB key " is displayed again on line 3):

Note:
If there are no Ethernet connection, the IP address won't show on the LCD screen.
